Use of ethanol free gas

Would the use of Ethanol free gas be an advantage for the Volt. My wife and I love our Black 2012 Volt and and taken many trips with it as we are retired. Is this something that is plus for the user if the ethanol free gas is available.

There are some advantages and disadvantages to ethanol-free gas, but the primary advantage is better fuel economy (by 2% to 5%, typically). That advantage is offset by a higher price, but it might be worth it for some people.

Well, that sort of depends on your view of why ethanol fuels are used in the first place. Ethanol fuels do have their positive side, otherwise they wouldn't be in the mix. I'm willing to bet that GM makes sure that their engines function as good as they can on ethanol fuels. Maybe in the big picture using ethanol fuels is more positive than negative.

I can get ethanol-free gas but it's only from one station and only in regular grade. Although the volt has cut my fuel use dramatically, I'm not going to be one of those facing maintenance burns so long term stability isn't an issue with me.

So here's my question: is ethanol-free regular better than premium with ethanol in terms of mpg? Price is about the same.

Most likely, but that is due to energy density. If your car is tuned for higher octane (typically very advanced ignition timing and high compression), a lower octane fuel (even if ethanol free) might cause the engine to retard to the point that you aren't seeing engine efficiency that you would normally see with the higher octane fuel. In my experience, very few factory cars are tuned so aggressively that they actually need premium grade fuel, but it some worst-case scenarios, it does become necessary.
